SF100AR0 Bearing Product Overview & Core Advantages
The SF100AR0 is a high-performance thin section angular contact ball bearing engineered for applications requiring exceptional precision and reliability. Constructed from stainless steel with a 30° contact angle, this single-row bearing is specifically designed to handle significant combined loads, including high thrust loads in one direction alongside radial loads. Its Reali-Slim cross-section provides a compact and lightweight solution, enabling space-saving designs without compromising on load capacity or performance, making it ideal for precision machinery and high-rigidity applications.
SF100AR0 Bearing Model Code Explained, Specifications & Naming Convention
| Suffix / Prefix | Technical Meaning |
|---|---|
| SF | Indicates the Stainless Steel construction of the bearing rings and balls. |
| 100 | Specifies the bore diameter of 10.0 inches. |
| A | Denotes the 30° contact angle, optimized for handling high axial loads. |
| R0 | Signifies the Radial Internal Clearance group (C0). |
| (Open) | The bearing features an open (unsealed) design, suitable for systems with external lubrication. |
SF100AR0 Bearing Structural Features & Performance Benefits
Superior Material Construction: Manufactured entirely from stainless steel rings and balls with a brass cage, this bearing offers excellent corrosion resistance and durability in harsh environments.
High Load Capacity: The angular contact design with a 30° contact angle enables the bearing to support substantial combined radial and axial loads, with a high static load moment of 41,620 lbf for exceptional stability.
Precision Engineering: Built to ABEC-1 tolerance standards with tight dimensional controls, ensuring smooth operation, reduced vibration, and high rotational accuracy for precision applications.
Optimized Thin-Section Design: The Reali-Slim profile provides a large diameter in a minimal cross-section (0.75" width), saving weight and space while maintaining structural integrity and high rigidity.
SF100AR0 Bearing Typical Application Areas
- Aerospace & Defense: Gimbal systems, radar platforms, and guidance mechanisms.
- Semiconductor Manufacturing: Wafer handling robots and precision stages.
- Medical Equipment: CT scanners, MRI machines, and surgical robots.
- Industrial Automation: Robotic arms, rotary tables, and precision indexing systems.
